- This is considered an Android Private function, not exported
for general use.
- goal is to retreive a file's content from a series of log
messages from pmsg, to be retrieved after a reboot for
transfer to a persistent location.
- files are presented in reverse sorted order, first based on
_any_ numerical content, then by alphanumeric order.
- Add a gTest for this function, relies on gTest for
liblog.__android_log_pmsg_file_write from prior to reboot.

- This is considered an Android Private function, not exported
for general use.
- goal is to record a file's content into a series of log
messages into pmsg, to be retrieved after a reboot for
transfer to a persistent location.
- filename reference is converted to a tag-unique
"<dirbase>:<filebase>".
- buffer and length representing the filename contents are
recorded, along with a sequence number placed into the nsec
time field to ANDROID_LOG_PMSG_FILE_MAX_SEQUENCE.
- Add a gTest for this function.

(cherry pick from commit 018a96d03f)
Create config_logger, logger and logger_read to house the log
interfaces. Add fake_logger, logd_logger and pmsg_logger to
house the write and read transports. Allows for an easier and
direct path to add new transports to the library.
SideEffects: None, logger benchmark performance unaffected

This works around b/21028929.
That old bug reappeared in nyc-dev because of file-based-encryption.

It was dropped in the migration to the public.libraries format
NDK is the same on standard Android and Wear.

Commit b82bab66 introduced the use of memory cgroups for keeping track
of forked PIDs; it basically creates a separate memory cgroup for every
process forked from zygote.
Each such memory cgroup which also have its own LRU with (in)active file
and anonymous pages. The current theory is this could potentially introduce
two problems:
1) kswapd runs longer because it has to iterate over the LRUs of all mem
cgroups, instead of over the LRUs of a single root mem cgroup;
2) the way kswapd reclaims things will be different also - I think it will
tend to bias reclaim to smaller mem cgroups, and process private pages
will end up on ZRAM swap much sooner.
Until we figure this out, fall back to the CPU accounting cgroup for keeping
track of forked PIDs. This leaves us with a single root mem cgroup again. We
can also keep userspace lmkd enabled because it only requires the root mem
cgroup.

This was actually nonfunctional until f5e8f0b, because it was using kill
after privileges were dropped. This doesn't seem necessary after the
changes to the sibling thread ptrace logic, though.

Use sigtimedwait on SIGCHLD to watch our forked worker processes for
failure, so that we can guarantee that we always resume/kill the target
process if libunwind crashes.

This list contains libraries that should directly or indirectly
be accessible to apps for the platform. Note that this list is
not device specific but rather device class specific.
For now we have 2 separate lists; one for Android Phones and Tablets,
and another one for Android Wear devices.

Add ability to use sdcardfs if kernel support is found.
In the future, we will likely remove the fuse components
entirely, but for now, just use sdcardfs when possible.
